Hello. Is it a known common problem to get a Sightmark Photon to "zero" and stay there? It seems that there is not enough adjustment in elevation to zero it? Also, seems that windage might drift (even on a .22 LR). The Photon in discussion has been tried on 2 different platforms, with same results. Any advice or feed back would be appreciated. Thank you.

I don’t mean to be a jerk when I say this, but it’s probably bc it’s sightmark. If you confirmed it on two rifles, it most likely has a wandering zero issue. I am not familiar with their internals. It could also be what the mounting system is on it coming lose.
Wandering zero. Place known good optic on same gun. Does it wander? If yes. Gun issue or mount issue. If no, optic issue.
Sightmark no bueno
On certain rifles you need to shim it. Use pieces of a beer can, bike inner tube, etc. You should be able to zero it then.
One platform is a 10-22, so recoil would not be causing mounting system to shift. And it has done it after only a few shots. Thanks.
Zero is like 1/2 MOA with another scope on the 10-22, and around 1 1/4 MOA on the other platform, so I think the rifle is ruled out as the problem. Everyone seems to be verifying my opinion. Thank you.
I am beginning to agree with your opinion on this. Thanks.
Indeed! It was first tried on a .223, then a .22LR, so it isn't like it was strapped to a .500 Nitro Express. I think it will become a hand-held viewer. Should work for that.
Good advice. I had not thought of that. I was of the opinion that even a cheap scope should be okay for armadillos at 50 yards or less, on a .22LR. It is sure worth trying shims. Thank you.
